69312 Rogerbacon           Discovered 1992 Sept. 24 by F. Börngen and L. D. Schmadel at Tautenburg.
English theologian Roger Bacon (1220?-1292), known as "Doctor Mirabilis" for his universal attainments, was a major proponent of experimental science. He studied mathematics, astronomy, optics and alchemy, and he tried to reform the theological methodology of his time. The name was suggested by the first discoverer.
